Answer:
3/2
Step-by-step explanation:
Pick two points on the graph
(-1,2) and (3,8)
We can use the slope formula
m= ( y2-y1)/(x2-x1)
= ( 8-2)/(3 - -1)
= (8-2)/(3+1)
= 6/4
= 3/2
Answer: The vertical stretch of 5 in the equation y = x is defined by
.
Explanation:
The given equation is,

It can be written as,

The function is defined as
.
If
, then the function has a vertical stretch by a factor of S units.
If
, then the function has a vertical shrink by a factor of S units.
Since we have to find the vertical stretch of 5 in the equation y = x.


The below figure shows the graph of y = x and
.
